> As a result of ISPN-6005, we decoupled the incoming Hot Rod server invocations from sending events by adding a intermediate queue that maintains the events to send to clients. However, this separation can lead to a Netty worker thread starvation issue since we add the events to the queue in Netty's IO thread, so if the queue is full, incoming requests are stuck.
